Technology for Millimetre Wave Radiometers

33rd European Microwave Conference, 2003, 2003
Technology for millimetre wave radiometers is discussed. Distinction between coherent and incoherent detection is also addressed. As an example, details of the 70 GHz ultra low noise and high stability receivers for the European Space Agency (ESA) Planck Mission is given. These receivers are part of the Low Frequency Instrument (LFI). The LFI receivers
